D-arabinitol 4-dehydrogenase

Template:Infobox enzyme In enzymology, a D-arabinitol 4-dehydrogenase (Template:EC number) is an enzyme that catalyzes the chemical reaction

D-arabinitol + NAD⁺ $\rightleftharpoons$ D-xylulose + NADH + H⁺

Thus, the two substrates of this enzyme are D-arabinitol and NAD⁺, whereas its 3 products are D-xylulose, NADH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is D-arabinitol:NAD⁺ 4-oxidoreductase. Other names in common use include D-arabitol dehydrogenase and arabitol dehydrogenase. This enzyme participates in pentose and glucuronate interconversions and fructose and mannose metabolism.
